Project Objectives
The objective of this project is to develop and test a methodology to produce spatially integrated sedimentological and morphological maps over the inshore continuum. The purpose is that this methodology can be applied in future studies; as such its set-up is ideally based on a dataset that is sufficiently detailed and diverse in terms of its sedimentology and morphology.
Methodology
As a spin-off project, INSHORE is not meant to develop new sensor technologies or new processing and analysis procedures. It will make use of existing technology and its innovative character relates to the combination of techniques, and their synergistic use in sedimentological applications. The basic idea is to couple airborne optical data to seaborne acoustic data in the view of covering the continuum of the seawall down to the seabed.
During the INSHORE project, some new approaches will be needed due to the combination of techniques and their synergistic use. As such, signal content information will be used to examine its contribution for the classification of the ground surface for morpho-sedimentary purposes. Another innovative aspect we want to highlight is the follow-up of nearshore feeder berms, especially in combination with backshore and foreshore nourishments. The evolution in time of these soft defence structures is not well-known yet, though very important to judge on the safety level of the seawall.
Results
The INSHORE project has a large technical component and will clarify issues on data merging and integration, resulting from optical/acoustic, airborne/seaborne technologies.
This know-how will be applied over the inshore continuum with the aim of studying its morpho-sedimentological state and dynamics. Its relevance will be illustrated related to coastal zone management and monitoring, including coastal erosion. At least for the Belgian research domain, the suggested approach is highly innovative and unique because, for the first time, an integrated, full-coverage and detailed output will be provided over the inshore continuum. This will yield new insights into: (1) the state and dynamics of foreshore and nearshore nourishment berms; (2) the near- to offshore sediment distribution tied to probable source areas; (3) the inshore continuum morphology with identification of morphological units; (4) the impact of beach nourishment works on the morphodynamics of the inshore continuum.
VITO Contribution
Firstly, based on hyperspectral CASI imagery a map of the dry beach will be made which classifies the sediments into sixteen detailed classes. These detailed classes from this sedimentological map will subsequently be merged into eight workable classes (the former DDK classes). Validation on the classification results will be done to get an idea about the classification accuracy. Secondly, using the LiDAR data, a beach morphological map will be made, which in combination with the sedimentological map will be used to interpret the sediment dynamics.
